Yes, you may run as many separate databases (we call them 'stones') as  
you wish, provided that each use fits within the license restrictions.  
If you really try to scale it you will probably need multiple hosts  
(real or virtual) since the single-CPU limitation is applied using  
processor affinity to CPU 0 (this means that multiple databases on the  
same host would all use the same CPU). Otherwise, as long as your data  
does not exceed 4 GB, you can likely do this sort of "horizontal"
